In the operation of such filter presses, a medium to be filtered - the "cloudy" - is fed under pressure to the filter chambers and pressed through the filter cloth, whereupon the solids content of the medium is deposited on the filter cloth as a "filter cake". The filtered medium (filtrate) flows below the filter cloth through an outflow from the filter chambers.

Abstract

L'invention concerne un procédé d'alimentation en agent liquide d'une chambre de filtration (15) qui est formée dans un filtre-presse dans un plan de séparation (16) entre deux plaques filtrantes (13) superposées en coïncidant. La chambre de filtration (15) est alimentée en cet agent par au moins une pluralité de canaux (10) étroitement juxtaposés à partir d'un petit côté (12) d'une plaque de filtration (13), ces canaux aboutissent directement dans les chambres de filtration (15) par des orifices de sortie (8). L'invention concerne également une plaque filtrante (13), un sabot de remplissage (1) et un dispositif d'alimentation destiné à une plaque filtrante (13) pour la mise en oeuvre du procédé. Pour réduire l'usure des canaux (l0), l'agent est cédé à chaque canal (10) par un orifice d'entrée externe (14) situé sur le petit côté (12) de la plaque filtrante (13) et les canaux (10) s'étendent séparément sensiblement parallèlement des orifices d'entrée (14) jusqu'aux orifices de sortie (8).
